HENRY ALBERS, OF NEW BREMEN, OHIO.

THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,502, dated March 16, 1880.

" Application led January 30, 1880.

To all whom it may concern:

Be it known that I, HENRY ALBEEs, a citizen of the United States, residing at New Bremen, in the county of l Auglaize and State of Ohio, have invented certain new and useful Improvements in (Phill-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

and to letters or gures of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in that class of devices known as thill-couplings;77 and it consists in the construction and novel arrangement of the various parts, as will be hereinafter more fully explained.

The annexed drawings, to which reference is made, fully illustrate my invention,in which- Figure l represents a top or plan view. Fig. 2 represents a similar view, part sectional. Fig. 3 represents a bottom view. Fig. et represents a vertical cross-sectional view, and Figs. 5 and 6 are detail views.

A designates one end of an ordinary vehicle-axle, provided with the usual clip B, to which the rear end of thills are attached.

G designates a spring coupling-pin, the solid end a of which passes through the eye a in the clip B, and enters the eye b of the thills b', thence, through the eye c, to the opposite side of the clip aforesaid. The longest portion c' of said coupling-pin forms a spring on which, and near the outer end thereof and opposite to the clip B, are made notches c2 c2, that engage with the inner face of an eye, d, on the short arm of a bar, D, that is secured to the clip and axle aforesaid. Said couplingpin C is provided with a detachable sleeve, c3, (of leather or any suitable material,) that covers the same, thus protecting the spring portion of the pin from getting filled with mud, and allowing it to be lreadily operated in attaching and detaching the same from the clip B.

,tioned.

E designates a spring having at one end upwardly-projecting lugs c c and a perforation, e', and bent in shape of the letter U, the free end e2 of which comes in contact with the end of the thills, and presses the latter against the solid portion a of the spring coupling-pin (l, thereby preventing the latter from rattling.

It will thus be seen by the foregoing description that I constructthe bar D, that supports and secures the spring-pin C, and the short arm d4, as well as the plate df, all of one piece, and the latter being secured to the clip B, holds the former firmly in place, and the eye d, on the short arm d4, somewhat larger than the thickness of the spring-pin C, allows said'pin to pass through the same and -enter the eyes a.' b c in the clip B and thills b', after which the notches c2 cl spring in and engage with said eye d, thereby securing the pin G with the coupling. Furthermore, the spring E, being secured to the clip B, and bent in the form shown in Fig. 4 of the drawings, with the free end pressing againstthe rear of the thills, prevents the latter from rattling, and the projections or lugs e e, overlapping the sides of the plate d', prevent lateral displacement of said spring; also, the detachable sleeve c3, surrounding the pin C, protects said pin from mud, Svc., as well as being ornamental.

Again, if there should be any strain on the clip, causing it to give in the least, the bar D will move with it and cause the pin to wear evenly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a chill-coupling, the bar D, short arm d, having the eye d and thecross-plate d',

made in one piece, in combination with the clip is prevented from lateral displacement, sub- B and spring-pin C, substantially as described, stuntially as described, and for the purpose set and for the purpose specied. forth.
